PRESSURE SPRAY AND WASHING DEVICE Filed June 15, 1947 r 2 Sheets-Sheet 2Patented Nov. 7, 1950 UNITED STATES PATENT OFFICE 1 Claim.

Thisinvention relates to a pressure spray and washing device and has forits primary object to.create a spray of washing fluid which may bedirected against the sides, or into objects to be washed.

Another object is to produce a continuous directed spray of washingfluid which will cover a relatively large area of the object beingwashed.

The above and other objects may be attained by employing this inventionwhich embodies among its features a pool of washing liquid; a rotorrotatably mounted above said pool of liquid with its lower portionsubmerged in the liquid in said pool, paddles extending outwardly fromthe periphery of the rotor for successive immersion in said liquid asthe rotor is rotated and means submerged in the liquid in said pool forcooperating with the paddles in forcing out of the pool the liquid whichlies adjacent the periphery of the rotor.

Other features include forming the paddles as spiral blades which extendoutwardly from the periphery of the rotor, and for substantially theentire length thereof, in such an arrangement that as the paddles aresuccessively moved through a circular path with the rotor the effects ofone paddle will overlap those of the other.

Still other features include means submerged beneath the surface of thepool for cooperation with the paddles in forcing out of the pool theliquid which lies adjacent the periphery of the rotor.

In the drawings- Figure 1 is a plan view of a pressure spray and washingdevice embodying the features of this invention;

Figure 2 is an end view of the device illustrated in Figure l;

Figure 3 is a transverse sectional view taken substantially along theline 33 of Figure 1;

Figure 4 is a longitudinal sectional view taken substantially along theline 4-4 of Figure 3;

Figure 5 is a perspective view of the rotor illustrating the paddles indetail, and;

Figure 6 is a perspective View of the liquid confining shield.

Referring to the drawings in detail a tank designated generallycomprising a substantially semi-circular bottom H closed by end walls I2is equipped with feet [3 which are designed to hold the tank level withthe open side disposed upwardly. Attached at opposite ends to the end'walls I2 are suitable bearings M, and fixed. to" one end" of the tank isa bracket 15 upon which. ai'suitable drive motor I6 is supported. Theaxis of the drive shaft H" of the drive motor: aligns: with the openingsin the bearings M- which in turn; lie along the longitudinal axis of:theatank, [8. previously referred to.

lvfountedl for: rotation in. thebearings 14, in axial alignment with thedrive. shaft l l of' the motor I6 is a drive shaft I81 carrying a'rotordesignated generally l9; and coupled in a conventional manner as at 20to the drive shaft lal' isrthe drive shaft. 18 so that the latter willrotate when. the motor [G is energized;

'Iihe rotor I9 above referred to comprises a circular cylindrical body2| carrying on its periphery a radially spaced group of, paddles 22 eachof which is of spiral form and extends throughout the entire length ofthe circular cylindrical body 2|. As illustrated in the drawings thepaddles 22 are arranged so that as the rotor rotates within the tank IQa paddle constantly is submerged in the liquid contained in the tank. Inother words as one paddle dips into the liquid the other is still beingwithdrawn therefrom so as to produce an uninterrupted stream of liquidfrom the apparatus.

In order to aid in the discharge of the liquid from the apparatus anarcuate shield 24 is provided and carries adjacent opposite endsslottedbrackets 25 through the slots of which adjusting screws 26 project intothe end walls l2 of the tank I 0. This shield 24 lies substantiallyconcentric with relation to the body 2| in spaced relation thereto sothat as the paddles 22 rotate with the rotor l9 they will pass near theconcave side of the shield to cooperate therewith in ejecting the liquidfrom the pool that lies adjacent the periphery of the rotor.

In order that the direction in which the fluid is ejected from the tankI B may be governed I provide each paddle with deflectors 21. Thesedeflectors 21 project from the advancing faces of their respectivepaddles and are arranged at varying angles to form pockets in which theliquid is trapped and elevated between the surface of the rotor and theconcave side of the shield 24. By arranging the deflectors at varyingangles the force of the spray may be governed and its direction ofpropulsion regulated according to the necessities of the service to beperformed. It will be understood of course that the proper rotor isselected having the arrangement of deflectors desired, and introducedinto the machine 3 to be coupled to the drive motor H5 in accordancewith the work to be performed.

In use it will be understood that with the tank H1 filled with thedesired washing and cleansing liquid, and the proper rotor I9 mounted inthe bearings l4 and coupled to the drive shaft of the motor l6, when themotor is set in operation the rotor will be driven to cause the paddles22 to move in a counter-clockwise direction when viewed from Figure 3and lift the liquid confined between the periphery of the rotor and theconcave face of the shield 24. Inasmuch as the rotor is directly coupledto the drive motor l6 it will be evident that it will rotate at the samespeed as the speed of rotation of the motor and consequently the sprayproduced by the device will be ejected from the tank with a forcegoverned only by the speed of rotation of the motor. By selecting therotor best suited to the purpose, the liquid trapped in the pocketsformed by the paddles and the deflectors may be ejected in varyingdirections according to the angular relation of the deflectors withtheir respective paddles.

While in the foregoing there has been shown and described the preferredembodiment of this invention it is to be understood that minor changesin the details of construction, combination and arrangement of parts maybe resorted to without departing from the spirit and scope of theinvention as claimed.

Having described the invention, what is claimed as new is:

A pressure spray washing device comprising a substantiallysemi-cylindrical trough, semi-circular end walls closing theends of saidtrough to 4 form a semi-circular container for washing liquid, a bearingmounted on the upper edge of each end Wall midway between opposite endsthereof, a shaft mounted in the bearings to rotate about a horizontalaxis which extends longitudinally of the container, an elongatedcircular cylindrical rotor mounted on said shaft to rotate therewithbetween opposite end walls of the container, a group of peripherallyspaced spiral paddles extending radially from said rotor, longitudinallyspaced spray deflectors extending angularly from the leading side ofeach paddle to form in conjunction therewith and with the rotor a groupof liquid receiving pockets, means to rotate the rotor at asubstantially constant speed, a curved shield in the container extendingbetween opposite end walls, said shield lying concentric with the rotorand means carried by the end walls and coupled to the shield adjustablyto hold said shield radially spaced from the rotor whereby the pressureof the spray created by rotation of the rotor may be varied.
